My invention relates to improvements" in crowning mechanisms, andit consls'tsin the combinations, constructions; and arrangements herein'fdesc'rihed and'claimed.

An object of'my jinvention isto' provide a crowning mechanism wliich'ha'snovel means for feeding crowns to the crowning unit at desired intervals. A further object ofmy invention is 'tolprovide a device of the type described which has novel meansrfor grippingthe crowns after they have been received by the crowning unit,

whereby the crowns may beheld against 'displacement until moved into-locking engagement withthe bottle." 7

A further object of my invention is to' provide a device of the type described whiehhas means for "automatically releasing the crowns at desired intervals and-rneansiorautomat ically holding the remainingeriowns,after one crown has been automatically in VA further object ofniy inventionjisftopro} v vide a deviceof the type described which has novel means for automatically{ removing the hopper in the crowns which pass from wrong'position.

Other objects and "advantages fwlll' appe r in the following specification, and the novel features of the invention will be particularlypointed ou't'in the appendedc'laims;

Crown chute receiving slots 31 are provided in the free ends, of the crown holders 25. Transversely extending cam surfaces 32 are provided at th outer extremities of the slots 31.

A head portion 33 is mounted upon the stationary supporting member lfas shown in Figure 2'. A crown hopper 34 is carried by the head portion 33 for receiving a plurality of crowns indicated at 35 in Figures 3 and 4. A positioning plate 36 is disposed in the hopper 34 and is provided with an annular groove 37 arranged to receive the crowns 35 inthe desired position for" directing the crowns from the hopper 34 through an outlet-38 and 7 into a'crown chute 39. An agitator40 is'disposed inthe hopper 34 adjacent thepla'te 36 and is mounted upon a shaft 41. The

shaft41 is provided withfa toothed portion 42, the teeth of which are in mesh with a rack 43. The rack 43 has its lower end operatively connected to the collar 3 and is arranged to be moved thereby.

crown chute 39is provided'with a discharg I .ing opening 49 whichis positioned between passageway 50.

the twocextr'emities of the crown ch'ute and:

which communicates with the passageway 50 in 'the'chute, A taperedsurfa ce' 51 is pro vided at the opening 49 for a purpose herein-'- after described. Spaced-apart guide strips 52 are secured to the crown chuteto form the V Acrown-r'etaining latch 53 is pivotally mounted at 54 upon the. lower end of the crown chute and has a finger 55 which extends inwardly for normally holding the crowns from passing from the chute. A trip pin' '56 is carried by the lower end of the chute .39 a short distance from" the crownretaining ,latch 53. A trip ,.lever 57 1s piv otally mounted upon one of the crown holders 25 and is normally held inahorizontal position by means ofa helical spring 58. The

trip lever is provided with a contacting shoulder 59 positioned substantially at its center and a cam surface tiq disposed at its outer end.-

i Acam' rollerlfilis rotatably carriedby the collar 3. A cam plate 62iis carriedbythe crown chute ,39 and is in engagement with the cam roller 61f "The-'upperiedge of the cam plate 62 istapered as at'63 for a purposehere- 1 inatter described. Y

From the foregoing descriptionof the various parts of the device, the operation thereof may be vreadily understood."- A bottle-supporting table 64 is provided for moving bottles 65 intermittently beneath and away from the crowning unit 8. When the crank shaft 7 is rotated and the device is set in motion, a reciprocatory movement is imparted to the V collar 3- and its cooperating parts. Let us assume that the collar 3andits'cooperating parts are in their uppermost position, as shown in Figure 3. ,VVhen the collar 3 is it moved downwardly, the crown will have been placedin the crown holder, as shown in Figure 2, and, as the crowning unit 8 is moved 'toward'one of the bottles 65, the plunger 15 will hold the'crown in engagement with the top of-the bottle while the top of the bottle passes between the segments 21. As the crown and the top of the bottle pass between the segments 21, the corrugated edge of the crown i's'bent inwardly around the head of the bottle, and thusfirmly secured inplace.

As the collar 3 and its cooperating parts move upwardly, the spring 18 holdsthe plunger 15 in engagement with the crown upon the bottle until the crowning unit has been removed from the top of the bottle. The

unit continues in'this movement upwardly,-

and in this movement'the cam roller 61 rides upon'the cam plate 62 until-it reaches the upper extremity of-theccam plate. Atthis position the crown chute 39 is allowed to swing inwardly about its pivot, as shownin Figure 4'thus moving the free end of the crown chute into engagementlwith the crown holders 25'.

fAj's "the lower end of the crown chute "39 swings inwardly, the 10am surfaces 46 contact with the surfaces 32 of the crown holders '25 and force the crown holders away from each oth'era' slightdistanc'ef During this move- 'men'tfthia"crown-retaining latch 53 engages withf theshoulder 59 of the'trip lever 57 thus swinging the finger portion 55 free from the adjacent crown and allowingthe crown to be passed inwardly and be received in the crown-retaining grooves 30. When the lower end of the crown chute reaches its innermost position, the cam surface 60 of the trip lever 57 'will have engaged with the trip pin 56 and will have been moved upwardly into theposition shown in Figure ,4; 111 this position the crown-retaining latch will be released and returned to its'inormal v position by means of the spring carried'there by+thusholding the remaining crowns in the crown chute. When the crown chute is moved away from thercrowning holders :25, 'thespring 27 will draw the crown holdersto;

'ge'ther thus frictionally holding the crown againstfldisplacement untilthe crowningunit is againmoved toward one of the bottles 65.

As the collar 3 is moved, theagitator 40' is oscillated, thus disturbing the crowns in the crown hopper 34 so that they will fall into the groove 37 Y and pass through the outlet 38 andintqfthepassageway 50 ot the crown chute 39. As the crowns pass into the passageway 50, they will be held by the crownretaining latch 35 and allowed to move downwardly as the crowns are removed therefrom. If any of the crowns should enter the passage way 50 in the wrong position, the projections upon the crowns will catch upon the tapered surface 51 and be thrown from the crown chute through the outlet 49. The handle 47 upon the crown chute provides a means for manually holding the crown chute from dispensing the crowns in the crown holders when desired.

it will therefore be observed that as the collar 3 is moved upwardly, the agitator 4:0

is actuated. causing the crowns to pass from.

the hopper into the crown chute, and, as the collar 3 reaches its uppermost position, the crown chute is allowed to swing inwardly, due to the fact that the cam roller 61 passes above the upper edge of the plate 62 and allows the plate to pass beneath the cam roller. During this swinging in of the crown chute, the crown holders 25 are forced apart, a crown is deposited in the crown-receiving grooves 30, and is held in place by the spring 27, when the chute is again swung outwardly. The crowns in the chute will be held by the crown-retaining latch 53 as the collar 3 is moved downwardly, bringing the crowning unit into operative engagement with one of the bottles 65 so as to cause the throat seg ments 21 to crimp the crown around the bead of the bottle. upwardly so as to allow the crowned bottle -to pass from beneath and another one of the bot les 65 to pass beneath the unit.
